Expressions and Equations Apply and extend previous understandings of arithmetic to algebraic expressions.
An algebraic expression is an expression that may contain numbers, operations, and one or more variables. A variable is a symbol that represents one or more numbers.
Summary We will write and evaluate algebraic expressions. We will represent the costs of items on a menu algebraically. We will translate verbal statements into numerical or variable expressions. For the equation 3 8 = 24, 3 and 8 are For the equation 3(2 + 6) = 24, 3 and (2 + 6)
Learning Outcomes: Explore the relationship between the two columns in a table of values Use a mathematical expression to represent a pattern
6.EE.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. Number Talks using expressions building expressions with algebra tiles or base base 10 blocks, label parts
